Tony,I wouldn't say that the gating increases the applied voltage.We already have the high voltage from the LC resonance.It doesn't need to be raised anymore.
Your second post is closer yet.
What do we need to do with the manually adjusted gate signal now that we have voltage?
We are no longer talking about resonance with the LC circuit,it no longer applies here,remember it was only for making the voltage.
What would the gate frequency now need to do with the voltage to get the water to pull apart?
OK we are making high voltage with an LC resonant circuit.Now look at it this way.Forget about how we got this voltage,by using a frequency driving circuit,and just look at it as high voltage.Why? Because thats all we need. The whole process of using an LC resonance circuit to create high voltage, is not needed for anything else.It is only meant to get us the voltage,nothing else.
So now what do we do with the high voltage only? Just think of it as voltage and nothing else,not even a pulsed voltage,just voltage.
We now use the gated frequency with this high voltage to do what?
Now take this info and go back to my other question,and think of a reason to use gating.
What is the main purpose of the Gated Pulse Frequency Generator?
To help you figure it out,ask yourself, Why is it manually adustable?
I figured this out over a year ago,and I have yet to see anyone mention this.If someone can come up with the answer I'm looking for,I will give you the schematic for that system.
Why am I not just giving it to you?
Becacause you all need to do the research yourself,thats the only way you'll learn.
this is what i came up with as the op amp side of the circuit
Top pin 1 in = ? signal, don't know what signal this one is Top pin 2 in = + 5 volts in not connected to pin 3 Top pin 3 in = Battery +12 volts in, not connected to trace on board Bottom pin 1 in = + 12 volts Bottom pin 2 in = J input Bottom pin 3 & 4 in = Ground
While working out the routing of the various circuits in the VIC card,I have found that there are four op amps on the one end of the board.Three of these op amps are shown in the schematic,and the fourth one is not.The very first one of the op amps, the one closest to the tabs that plug the board in,is not in the schematic,and gets a signal from some source,and the second op amp gets a signal from the GMS control panel circuit Analog Voltage Generator.Now these two signals come into the coil pack through the nine pin connector and pass into this board.What I have found is that the first two op amps are wired in parrallel and go into the third one.There seems to be two different signals coming into these first two op amps,and are being joined.
Ok so my question to you all is, what other signal could be coming into these op amps? What purpose would it be to join two signals together through op amps?
Ali,the scan from this circuit took about 3 seconds like Tony says.I seen it working first hand.And the scan didn't go from 0-10khz.It had a center adjust pot on the board,that allowed you to raise or lower the frequency range.For example the the scan may go from 2khz to 8khz,then if you adjust the pot up so it starts at 4khz than it will go to 10hz.So it could go as low as 0kz and up to 10khz,but not in one setting.
Tony,the 4017 weren't even hooked up on this board and they don't effect the output in any way.
Ali,the cap is a 10 uF.I have a better picture of it.
Webmug, those test of my coils were done with the scope probe connected to one side of the secondary coil and the ground clip connected to the other side of the secondary coil.It didn't make alot of differance if the ground clip was hooked up or not.I first connected the probe,and there was voltage being read,then I connected the probes ground and didn't see a change.The rest of my tests were done with both connected.When I test my whole vic,I ground the probes ground to my dc power supply output ground.
Tony, I seen Stans scanning circuit running and it would take between 2-3 seconds to go each way.
Donald, Half of the Voltage Amplitude Control, (figure 4) is on that card,the other half is with the vic coils. All of the Cell Driver Circuit (figure 5) is on that card. All of The Phase Lock Loop Circuit (figure 7) is on that card. All of The Resonant Scanning Circuit (figure is on that card. All of The Pulse Indicator Circuit (figure 9) is on that card. The Variable Pulse Frequency Generator (figure 12), the Gated Pulse Frequency Generator (figure 6),the Analog Voltage Generator (figure 3) were all in the GMS control panel.
There was a cover on the bottom of the cell chamber,that covers the wire from view.Also there was a positive and a negative wire for every tube set,and not just one positive going to all tubes.
The water is pumped up through every tube set and it goes out through the large hole in the center of the cell chamber back to the holding tank. Don
my cores are UR64/40/20-3F3 I've changed coils so often since that post,I don't know where I'm at now.My latest coils resonate @ 30khz. My coils are made to fit the window area of each side,can't make them any longer. Don
sebosfato, that isn't a tube in the center under the plate,it's a piece of stainless bar stock that is used for the negative wire hook up.It has a hole drilled and tapped in the center.There was an "O" ring that went between it and the bottom of the cell,to seal the bolt that went out the bottom.I took it apart because it was leaking,so I replaced the "O" ring.Thats why I took it apart,just took pics while I was at it. The color of the tubes is from the brown scum that comes out of the water when runing it.Over time it discolored the tubes.It does come off if you rub it. Don
1kv is just what it makes with these coils.I didn't set it up to that value.I will probably wind new coils to get around 2kv.Stan states that around 1kv the water molecule starts to elongate.So I want to be over that mark. Don
My measurements are of the coils themselves.My cell is a 3" tube set covered in delrin with tap water.All coils were measured with a B&K LCR meter with all the coils on the core,and all leads open,not connected to anything. Stan's coils were all the same size wire and thats what I did as well.Power going to the cell is so small,large wire isn't needed. Don
I had the same results as you with the diode across the primary coil,so I took it out as well.I'm not sure if there was one in Stans setup.It wasn't on the coil pack. Don
HM,there was two TIP120 transisters under the 2n3055.One of the TIP120 was the primary coil driver and the other was part of the amplitude control.The blocking diode is between the blue and red coils on the right side.That would be the secondary and choke.The blue box on the bottom is a female connector.A PLL board plugged into that socket.The serial connector would be for the voltage amplitude hook up. The four studs are the power in and pulses out to primary coil.Q5-Q9 are not on this coil pack,they would be on their own board. All coils were the same size 29-30.Iv'e stated that before.I used that for my primary and 35 for secondary and chokes.It allows me to have more turns on them with the same size bobbins.I dont know the resistance or inductance of these coils.Can't help you there.The resistors were all tied together as one.They seemed to be across the feedback winding. Remember that these coils were hand wound,and not at all precision.I don't think that their sizes make much difference.It only makes more or less voltage,and changes the resonance frequency Don.
Donald,the laminate material could be used,but it may not work as good as ferrite type.It might saturate at the higher frequencies the cell needs to resonate at.You could try it,it can't hurt. As for the the coil pack,there isn't any circuits on that card.There's a 5 volt regulator,and a 2n3055 transistor for the voltage amplitude control circuit.There was a resistor in line with the primary,thats not in Stans original schematics.The blocking diode is there too,the one Stan said was used.Thats all there is on that card. Don
is on that card.
